Saunder (crater)

Saunder is a lunar crater located in the central highland region of the Moon, to the east-northeast of the walled plain Hipparchus, named after Samuel Arthur Saunder. The outer wall is irregular and broken in several locations, forming the overall shape of a pentagon. The interior of Saunder has been flooded with lava, forming a level surface just below the rim. The floor lacks a central peak, but there are low rises in the southeast quadrant and a tiny craterlet towards the north rim.
